Abstract

We propose a single phonon source based on nitrogen-vacancy (NV) centers, which are located in a diamond phononic crystal resonator. The strain in the lattice would induce the coupling between the NV centers and the phonon mode. The strong coupling between the excited state of the NV centers and the phonon is realized by adding an optical laser driving. This four-level NV center system exhibits coherent population trapping and yields giant resonantly enhanced acoustic nonlinearities, with zero linear susceptibility. Based on this nonlinearity, the single phonon source can be realized. We numerically calculate g(2)(0) of the single phonon source. We discuss the effects of the thermal noise and the external driving strength.

Fig. 1. (a) Schematic diagram of the phononic crystal: the NV center ensembles are located near the surface. The phonon is coupled to NV center ensembles driven by the laser field and micro-magnetic field. (b) Energy levels of NV centers. In this structure, we regard |−1⟩, |0⟩, |+1⟩, and |Ey⟩ as |1⟩, |2⟩, |3⟩, and |4⟩, respectively. δ and ε are the detuning frequency. ωm, ωd, and ωc are the frequencies of the phonon, optical laser driving, and micro-magnetic driving, respectively.

Fig. 2. (a) Evolution of the second correlation function g(2)(0). (b) Evolution of the population of Fock state |1⟩. The coupling strength g/2π=25kHz, the dissipation of system γ=g/8, and the driving strength is Ω˜=g/5. The mean thermal polariton number of the blue dashed line, the red dotted dashed line, and the yellow line are ⟨P0†P0⟩=0.1,0.3,0.5, respectively.
